LOADING AND UNLOADING MECHANISM.

Specification of Letters Patent.

Patented May 25, 1809.

' Application filed September 28, 1908. Serial No. Lt55,024.

To allwhom it lmay concern:

Beat known that I, GRANviLLn Davis, of North Salem, county of I'Ieiidricks, and State useful Loading' and Unloading' Mechanism; and I do hereby declare that thefollowingil is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like figures refer to like parts.

The object of this invention is to rovide The particular device shown and described herein is for loading' shocks of corn in the to such use, for it can be employed as well for loading' hogsheads, barrels, bales and like heavy articles that` arc nioi'e or less uniform in shape and size.

The chief feature of the invention consists body or frame ofthe vehicle so that it will be slidable thereon as well as fulcruined thereto, whereby said loader can be turned down vertically beside the article to be loaded and the article coiinectcd therewith and then tin` and drawnnpon the plat form in the linal poil. ith this feature is not loadei'l will not extend materially beyond the sides of the platform and yet when the vehicle is in position for loading7 the loader can be pushed laterally to the ful cruined position. at the edgoof the platform the article, and after th(` article has been loaded it will not proiecl' lnaterially beyond the side of thi` platform. 'lhcsc advantages not only result from this in vcntion but it onablcs the ready unloading` of the article` by a incre reversal of thc loading' operation, so that the device used notonly as a loader lhis rinitcniplatcs that is, for cach shock of corn, hogshead, or balcof `cotton, and that said shock,` hogshcador bale remain on the loader during' transportation Along with the fore, '1'oing` is thel arrangeon inthe and be siidable thereoverand readily reinova ble entirely.

Hence, another feature of the invention consists in providing' a pivot rod along' each side of the platform and providing' number of loaders with the fulcruining means mentioned soL that any loader can be placed en,

' shocks of corn, the taperingT end or top of one shock will lie 'beside the widened end or butt of the adjacent shock and various shocks lit closely together against each other to matie up a load. `With a wagon of usual dimensions siX shocks of corn, three on each side,

can be carried in one load.

T is thc saine after the shock' and loader haw. been drawn nerr/:om tally toward tho middley of the vehicle plat-v foi'in. Fig. .S is a central, vcrt-iczil--scclion through the upper ond of the loader. Fig'. l) is an ond elevation of the left hand half of the vehicle with a lpadcr and shock of corn therepositions they occupy while being unloaded.V

ln the drawings herein is a vehicle, and hand horizontally 0H the platform as far 11 the platform thereof.

12 is the tongueV which, however, is shownpartially broken away. Alongeach side of.- the platform 11 there. is a fulcrum rod 13 eX- tending for the full length of thevehicle and held a slight distance from the 'edge of the latform by arms 14secured tothe platform. his gonstitutes the various features forming an integral part of the vehicle.'

VThe oader is separable from the vehicle and there may be any number of them and j shaped so as to accommodate themselves to the sort of article that is to be loaded. For

instance, bales, hogsheads and shocks of corn would require loaderssomewhat differently shaped. The loader herein shown is `for outer end is very wide, While the inner end is very narrow, thus conforming in a general Way to the shape of the shock of corn.

The loader is fulcrum'ed to a fulcmm rod 13 by a fulcrum late 17 secured near the upper part of the ottom or back 15 thereof and projects/outwardly or downwardly for a considerable distance, almost to the lower .or ter'kend of the loader and parallel with the bottom or back thereof, as appear in Figs. 4 .and 5. It rides and bears on roller 36 mounted on the rod 13. It is obvious, therefore, that this enables the loader to be readily removed or put in place on the rod 13 and serves to fulcrum the loader on `said rod and at the same time permits the loader to be drawn across the rod in one direction or the other, either for lowering the 'loader to the shock or for drawing it`and the shock upon the platform. At the outer or lower end of 4'5 \.the loader there are a pair of stops 18 turned to a position to engage the rod 13 when the loader is drawn horizontally upon the platform.

On the upper end of the loader there are pulleys 20 and 21 between which a cable 22 extends and near the middle of the loader there is an anti-friction roller 23 mounted in connection therewith inp'ositi'on to roll on thc platform as the loader is moved horizon- 'tally thereon. One end of the cable 22 may pass under the'rod 13 at the opposite side of the wagon and has a swingletree 24 thereon so that a horse can be hitched to it for loading purposes. The other end- `of ythe cable runs under a pulley '25 about midway and thence in position to be fastened around the .'shoc'k of corn.

- The operation of the\mechanism is as follows: The vehicle or wagon is driven near a shock-of corn and one of the` loaders is pushed is turned downwardly into a vertical position,

immediately beside the shock of corn so that the loader will be adjacent it. Then the cable 22 is fastened about theshock of corn and the horse hitched at the other end of the cable pulls the cable. The first effect of the pulling of the horse is to tighten the cable around the shock of corn and draw it snugly against the loader but when that has been done a further pull of the horse on the cable tends to tilt the loader from a vertical to a horizontal position, the loader carrying the shock with` 1t. When the loader has reached almost a horizontal position, its outer end and the butt of the shock will extendv quite a distance beyond the side of the platform, but then the position of the loader has become so nearly horizontal that the further pull of the cable draws it horizontally over and along the top of the platform and the shock is carried with it'until the stops 18 on the loader engage the rod 13 and stops the loading movement. The horse is then detached and -assh'own in Fig. 1, and the vehicle movedw i it will be obvious that the loader and shock will be n on the middle portion of the plat-V form, at east the same will not extend materially beyond thev side of the platform. After a shock has been thus loaded the ve hicle is driven to another shock and it is taken in on the opposite side of the vehicle and the process continuedA until say six shocks have been loaded. This constitutes a load.

For unloading, all that is necessary to be done is to slide the loader outwardly on the platform of the vehicle until it over-balances and then the shock Will .drop down into its original vertical position and after releasing the cable the loader can then be returned to the platform.

For loading and unloading other articles than shocks of corn substantially the same o eration is pursued as in the case of the s ocks of corn. I do not wish to be limited to a horse for pulling the loaders into position for the same may be otherwise done.

To hold the cable or rope 22 taut and from slipping lbackward gripping means 40 are provided substantially as shown in Fig. 8, consisting of upper and lower pawl-like members with their free ends meeting each other and pivoted at their remote ends to the upper part 16 of the loader frame 15 and spring-pressed toward the rollers ZU'and 21 in position to grip the cable When-it isV relaXed, to ermit the drawing movement-` thereof vwhi e tightening the cable around .the
